Why are alternating pumps used in standby mode?
One argument for alternating pumps is that the standby is known to be ready to operate. Test starts of standby pumps should therefore be implemented to ensure it is available, with the frequency of such starts determined by the pump and the operating fluid.
What should I do if my pump is on standby?
Should a manufacturer already use standby pumps, the recommendation is to analyse the system including the type and age of pumps, availability of test data and the fluid medium itself to determine where improvements can be made.
What do you need to know about starting a pump?
The pump you are about to start must be properly vented and primed. The suction valve must be fully open. The discharge valve may be closed, partially open or fully open; it depends on several factors that are covered later in part two.
Do you have to Prime a pump before startup?
Often misunderstood, or simply overlooked, the pump must be primed prior to startup. Even a self-priming pump must be primed the first time. The brief definition of primed means that all the air and noncondensable gases are removed from the pump and suction line and that only liquid is present in the system.

How to troubleshoot your pool pump ( quick and easy )?
1 Solution. For cavitation, the solution could be as simple as clearing a clog out of a plumbing line, or it could also be an air leak somewhere in your system. 2 Solution. At this point you can either replace the defective part or call a professional. 3 Solution.
How does a positive displacement pump get started?
You can fill the suction line with liquid and the foot valve will hold it in the line until the pump is started. The use of an external means of drawing a vacuum on the suction line. This can be accomplished with a vacuum pump and ejector or an auxiliary pump—typically a positive displacement pump.
